For a time, their shared life appears idyllic, built on a foundation neither could have predicted from such a disastrous beginning. However, the fragile peace is shattered when Endou crosses paths with one of Okumura’s former lovers. Through this encounter, he uncovers a deeply unsettling suspicion: Okumura may be secretly cheating on him. The revelation plunges Endou into a painful dilemma, forcing him to confront the very betrayal he once inflicted upon another man. Now, trapped between lingering guilt and newfound heartbreak, Endou must decide how to face the partner who turned his greatest mistake into an unexpected future.
